Description

Technical Field

[0001] The utility model relates to the field of textile equipment, in particular to a yarn guiding device of a spinning machine. Background Art

[0002] Textiles twist many plant fibers together to spin them into threads or yarns, which can be used to weave cloth. The earliest spinning machine was very simple and was used in the 14th century. After the 18th century, people invented better spinning machines, which made the textile industry the largest industry. All spinning machines only do two things: first, a large number of short fibers are aggregated into loose cotton threads, and then the cotton threads are pulled out little by little and twisted into fine cotton threads. The cotton threads become longer after twisting, and the longer cotton threads need to be collected by the yarn guide roller, so a yarn guide device is needed to complete the yarn collection.

[0003] Since the yarn guide device in the prior art solution is mostly in a fixed state in structure, the yarn guide device cannot adjust the left and right limit distance according to the size of the yarn guide roller, so that the yarn guide device can only be installed on yarn guide rollers of the same size, which causes the yarn guide device to be limited in use. Utility Model Content

[0004] The embodiment of the present application provides a yarn guiding device for a spinning machine, thereby solving the problem that the yarn guiding device in the prior art solutions is mostly in a fixed state in structure, and therefore the yarn guiding device cannot be adjusted to the left and right limit distance according to the size of the yarn guide roller, so that the yarn guiding device can only be installed on yarn guide rollers of the same size, which leads to the technical problem that the yarn guiding device is limited when in use.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A yarn guiding device for a spinning machine comprises a base, a supporting assembly for supporting a yarn guiding roller, a sliding device for driving the supporting assembly to slide, a rotating device for driving the yarn guiding roller to rotate, and a supporting slide rail arranged on the base; the supporting assembly is slidably connected to the supporting slide rail; the rotating device is installed on the left side of the base; the sliding device is arranged at the bottom end of the base; and the sliding end of the sliding device is transmission-connected to the supporting assembly.

[0007] A further technical solution is: the supporting assembly includes a ball bearing, a bearing seat for supporting the ball bearing, a supporting sleeve for supporting a yarn guide roller, a first fixing part for locking the yarn guide roller, and a slider sliding on the supporting slide rail; the ball bearing is arranged in the bearing seat; the bearing seat is arranged on the top of the slider; the supporting sleeve is arranged on the inner ring of the ball bearing; two groups of the first fixing parts symmetrically arranged are arranged on the supporting sleeve; the slider is arranged on the sliding end of the sliding device.

[0008] A further technical solution is: the sliding device includes a gear, a first driving device installed at the bottom of the slider and a rack arranged at the bottom end of the base; the gear is arranged on the output shaft of the first driving device; and the gear is meshed and connected to the rack.

[0009] A further technical solution is: the rotating device includes a rotating sleeve, a second driving device for driving the rotating sleeve to rotate, and a second fixing part for locking the yarn guide roller; the rotating sleeve is arranged on the output shaft of the second driving device; the second driving device is installed on the left side of the base; and two groups of the second fixing parts arranged symmetrically are arranged on the rotating sleeve.

[0010] A further technical solution is that the first fixing member and the second fixing member are both bolts.

[0011] A further technical solution is: the first driving device and the second driving device are both motors.

[0012] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0013] 1. Due to the use of the base, support assembly, sliding device, rotating device and supporting rail, when the yarn guide roller needs to be installed, the staff first fixes one end of the yarn guide roller on the rotating device, and then drives the support assembly to slide on the supporting rail through the sliding end of the sliding device, so that the support assembly slides to the position of the other end of the yarn guide roller, and then fixes the other end of the yarn guide roller on the support assembly to complete the installation of the yarn guide roller. At this time, the staff can drive the yarn guide roller to rotate between the rotating device and the support assembly through the rotating device. Since the sliding end of the sliding device can drive the support assembly to slide on the supporting rail, the distance between the support assembly and the rotating device can be adjusted, and then the yarn guide rollers of different sizes can be fixedly installed between the rotating device and the support assembly, thereby greatly improving the practicality of the yarn guide device of the spinning machine to a certain extent.

[0014] 2. Due to the use of the ball bearing, bearing seat, support sleeve, first fixing member and slider, when the sliding device drives the support assembly to slide to the other end of the yarn guide roller, the other end of the yarn guide roller is just embedded in the support sleeve, and then the staff raises and tightens the two groups of first fixing members at the same time, so that the ends of the two groups of first fixing members are against the other end of the yarn guide roller at the same time, and the other end of the yarn guide roller can be fixed. Since the support sleeve is fixedly connected to the inner ring of the ball bearing, when the yarn guide roller is driven to rotate by the rotating device, the other end of the yarn guide roller can be rotated together with the inner ring of the ball bearing through the support sleeve. Due to the use of the gear, the first driving device and the rack, when the position of the slider needs to be adjusted, the gear is driven to rotate by the output shaft of the first driving device. Since the gear is meshed and connected to the rack, and the rack is fixedly connected to the base, when the gear rotates, the gear will roll along the rack. When the gear rolls along the rack, it will drive the slider to slide on the support rail. The distance between the supporting assembly and the rotating device can be adjusted by sliding the slider on the supporting slide rail.

[0015] 3. Due to the arrangement of the rotating sleeve, the second driving device and the second fixing part, when one end of the yarn guide roller is plugged into the rotating sleeve, the staff can fix the yarn guide roller in the rotating sleeve by tightening the two groups of second fixing parts in sequence so that the ends of the two groups of second fixing parts are simultaneously against one end of the yarn guide roller. At this time, the staff can drive the rotating sleeve to rotate through the output shaft of the second driving device to realize the rotation of the yarn guide roller. The whole operation process is simple and reliable, which is convenient for the staff to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The embodiment of the present application provides a yarn guiding device for a spinning machine, thereby solving the problem that the yarn guiding device in the prior art solutions is mostly in a fixed state in structure, and therefore the yarn guiding device cannot be adjusted to the left and right limit distance according to the size of the yarn guide roller, so that the yarn guiding device can only be installed on yarn guide rollers of the same size, which leads to the technical problem that the yarn guiding device is limited when in use.

[0022] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] A yarn guide device for a spinning machine, such as Figure 1 As shown, it includes a base 1, a support assembly 2 for supporting a yarn guide roller, a sliding device 3 for driving the support assembly 2 to slide, a rotating device 4 for driving the yarn guide roller to rotate, and a support slide rail 5 arranged on the base 1. The support assembly 2 is slidably connected to the support slide rail 5. The rotating device 4 is installed on the left side of the base 1. The sliding device 3 is arranged at the bottom end of the base 1. The sliding end of the sliding device 3 is transmission-connected to the support assembly 2.

[0025] The support rail 5 is fixedly connected to the base 1. The rotating device 4 is detachably fixedly installed on the left side of the base 1 by bolts. The sliding device 3 is fixedly connected to the bottom end of the base 1. Since the sliding end of the sliding device 3 is transmission-connected to the support assembly 2, the sliding device 3 can be driven to slide back and forth on the support rail 5 through the operation of the sliding device 3.

[0026] Due to the arrangement of the base 1, the support assembly 2, the sliding device 3, the rotating device 4 and the supporting slide rail 5, when the yarn guide roller needs to be installed, the staff first fixes one end of the yarn guide roller on the rotating device 4, and then drives the support assembly 2 to slide on the supporting slide rail 5 through the sliding end of the sliding device 3, so that the support assembly 2 slides to the position of the other end of the yarn guide roller, and then fixes the other end of the yarn guide roller on the support assembly 2, and the installation of the yarn guide roller can be completed. At this time, the staff can drive the yarn guide roller to rotate between the rotating device 4 and the support assembly 2 by working through the rotating device 4. Since the sliding end of the sliding device 3 can drive the support assembly 2 to slide on the supporting slide rail 5, the spacing between the support assembly 2 and the rotating device 4 can be adjusted, and then the yarn guide rollers of different sizes can be fixedly installed between the rotating device 4 and the support assembly 2, so that the practicality of the yarn guide device of the spinning machine is greatly improved to a certain extent.

[0027] like Figure 2 and Figure 3As shown, the support assembly 2 includes a ball bearing 21, a bearing seat 22 for supporting the ball bearing 21, a support sleeve 23 for supporting the yarn guide roller, a first fixing member 24 for locking the yarn guide roller, and a slider 25 sliding on the support slide rail 5. The ball bearing 21 is arranged in the bearing seat 22. The bearing seat 22 is arranged on the top of the slider 25. The support sleeve 23 is arranged on the inner ring of the ball bearing 21. Two groups of first fixing members 24 are arranged symmetrically on the support sleeve 23. The slider 25 is arranged on the sliding end of the sliding device 3.

[0028] The sliding device 3 includes a gear 31, a first driving device 32 installed at the bottom of the slider 25, and a rack 33 arranged at the bottom end of the base 1. The gear 31 is arranged on the output shaft of the first driving device 32. The gear 31 is meshedly connected to the rack 33.

[0029] The ball bearing 21 is fixedly connected in the bearing seat 22. The bearing seat 22 is fixedly connected to the top of the slider 25. The support sleeve 23 is fixedly connected to the inner ring of the ball bearing 21. Two groups of first fixing members 24 are symmetrically arranged on the support sleeve 23. Both groups of first fixing members 24 are preferably bolts. Both groups of first fixing members 24 are threadedly connected to the support sleeve 23. The slider 25 is fixedly connected to the sliding end of the sliding device 3. The first drive device 32 is detachably fixedly installed at the bottom end of the slider 25 by bolts. The first drive device 32 is preferably a motor. The gear 31 is fixedly connected to the output shaft of the first drive device 32. The two ends of the rack 33 are respectively fixedly connected to the bottom ends of both sides of the base 1.

[0030] Due to the arrangement of the ball bearing 21, the bearing seat 22, the support sleeve 23, the first fixing member 24 and the slider 25, when the sliding device 3 drives the support assembly 2 to slide to the other end of the yarn guide roller, the other end of the yarn guide roller is just embedded in the support sleeve 23, and then the staff increases and tightens the two groups of first fixing members 24 at the same time, so that the ends of the two groups of first fixing members 24 are simultaneously against the other end of the yarn guide roller, and the other end of the yarn guide roller can be fixed. Since the support sleeve 23 is fixedly connected to the inner ring of the ball bearing 21, when the yarn guide roller is driven to rotate by the rotating device 4, the other end of the yarn guide roller can be rotated together with the inner ring of the ball bearing 21 through the support sleeve 23. Due to the arrangement of the gear 31, the first driving device 32 and the rack 33, when the position of the slider 25 needs to be adjusted, the output shaft of the first driving device 32 drives the gear 31 to rotate. Since the gear 31 is meshed and connected to the rack 33, and the rack 33 is fixedly connected to the base 1, when the gear 31 rotates, the gear 31 rolls along the rack 33. When the gear 31 rolls along the rack 33, the slider 25 is driven to slide on the support rail 5. By sliding the slider 25 on the support rail 5, the distance between the support assembly 2 and the rotating device 4 can be adjusted.

[0031] like Figure 4 As shown, the rotating device 4 includes a rotating sleeve 41, a second driving device 42 for driving the rotating sleeve 41 to rotate, and a second fixing member 43 for locking the yarn guide roller. The rotating sleeve 41 is arranged on the output shaft of the second driving device 42. The second driving device 42 is installed on the left side of the base 1. Two sets of second fixing members 43 are arranged symmetrically on the rotating sleeve 41.

[0032] The second driving device 42 is preferably a motor. The rotating sleeve 41 is fixedly connected to the output shaft of the second driving device 42. The second driving device 42 is detachably fixedly installed on the left side of the base 1 by bolts. Two groups of symmetrically placed second fixing members 43 are provided on the rotating sleeve 41. Both groups of second fixing members 43 are preferably bolts. Both groups of second fixing members 43 are threadedly connected to the rotating sleeve 41.

[0033] Due to the arrangement of the rotating sleeve 41, the second driving device 42 and the second fixing member 43, when one end of the yarn guide roller is inserted into the rotating sleeve 41, the staff can tighten the two groups of second fixing members 43 in sequence so that the ends of the two groups of second fixing members 43 are simultaneously against one end of the yarn guide roller, so that the yarn guide roller can be fixed in the rotating sleeve 41. At this time, the staff drives the rotating sleeve 41 to rotate through the output shaft of the second driving device 42, so as to realize the rotation of the yarn guide roller. The whole operation process is simple and reliable, and it is convenient for the staff to operate.
